Abstract

The purpose of this study is to review that the VE techniques can be used as a selection tool of borrow pit locations. The analysis of the soil investigation report is performed for the selection of proposed borrow pit site on a large-scale residential development area. Possible earthwork volume of mining is estimated and the weighting matrix evaluation is applied to the VE techniques. After determining the evaluation items for VE assessment, important degree was calculated. The Rating and evaluation of performance is carried out on a proposed borrow pit site. And, development priority has to be decided for a proposed borrow pit sites. As a result, the relative construction cost is closely related to the haulage distance. As the haulage distance increases, the relative construction cost will be increased. Therefore, it was confirmed quantitatively that haulage distance has a significant impact on the select of borrow pits. Also, it was found that the condition of borrow pits itself is important, but it cannot be ignored the impact of the life cycle cost for the selection of optimal borrow pit sites.

본 연구에서는 Value Engineering 기법을 토취장 선정의 도구로 활용할 수 있는지의 여부를 검토하였다. 이를 위해 대규모 택지개발지역의 토취장 후보지들에 대한 지반조사 결과를 분석한 후 토취장 후보지들의 가채량을 산정하였으며, 토취장 후보지들의 VE 평가에는 가중치 부여 매트릭스평가법을 적용하였다. VE 평가를 위해 평가항목을 결정한 후 중요도를 산정하고 평가척도를 설정하였으며, 토취장 후보지에 대한 성능등급 및 성능평가를 수행하여 토취장 후보지들의 개발 우선순위를 결정하였다. 결과적으로 토취장 후보지들에 대한 상대공사비는 운반거리와 밀접한 관련이 있으며, 운반거리가 멀어질수록 상대공사비는 점차 증가하므로 운반거리가 토취장 선정에 있어 상당한 영향을 미친다는 것을 확인하였다. 또한 최적의 토취장 후보지를 선정하는데 있어 토취장 자체의 조건도 중요하지만, 생애주기비용의 영향을 무시할 수 없는 것으로 나타났다.
